Joe Hammer is thinking about setting up a special counter for the do-it-yourself customers at which they can get, not only help where to find products in the store, but also some quick advice about the best way to handle their upcoming projects. Experience has taught Joe that six minutes is a good figure to allow for the average time required to serve a “do-it-yourselfer” and that these customers will arrive every 15 minutes throughout the day.

a.) If joe sets up the counter under these conditions, what operating characteristics might he expect?

b.) What might Joe do to avoid the costs of idleness?

c.) What is the likelihood(probability) that three or more customers will be at the counter, either waiting or being served, at any given time?

Calculate the Utilization rate, idleness rate, Average time in queue, Average time in system, Average number in queue, Average number in system, and probability that three or more customers will be in the counter system at the same time. Can you please show calculation for P_0, p_1, p₂, p₃ please.

The Sarbanes Oxley (SOX) Act was passed in 2002 as a result of corporate scandals and in as attempt to regain public trust in accounting and reporting practices. Two random samples of 1015 executives were surveyed and asked their opinion about accounting practices in both 2000 and in 2006. The table below summarizes all 2030 responses to the question, “Which of the following do you consider most critical to establishing ethical and legal accounting and reporting practices?” Did the distribution of responses differ from 2000 to 2006?

1. Determine and state whether this is a test of Goodness of Fit, a test of homogeneity or a test of association (or independence). Include in your statement a justification for your choice.
2. Write the correct Null and Alternate Hypotheses for the test
3. Perform the test using Minitab (remember to include the output in your Word document)
4. State your decision, and why you made this choice
5. Give a conclusion in the context of the problem. If you make the decision to reject the null hypothesis, be sure to comment on the bar chart.

According to the 14th Annual RBC Homeownership Survey conducted by Ipsos Reid in 2007, most Canadians thought purchasing a home is a good investment. Additionally, there was less concern about interest and mortgage rate hikes than at the same time the year before: 51% were concerned about interest rate increases in 2007 versus 56% in 2006; 43% thought mortgage rates would go up in 2007 versus 70% in 2006. Suppose that these results are based on 1000 randomly selected adult Canadians.

(a) (3 pts) Construct a 93% confidence interval for the proportion of Canadians who were concerned about the mortgage rate increase in 2007.

(b) (3 pts) Construct a 98% confidence interval for the difference in the proportion of Canadians who were concerned about the mortgage rate increase in two years.

(c) (7 pts) Use the p-value method to test if the proportion of Canadians who were concerned about the interest rate has decreased from 2006 to 2007 at the significant level 1%. (d) (3 pts) Interpret the p-value for the test in part (c).

Romsen Manufacturing, Inc., a producer of precision machine parts, uses a predetermined
overhead rate to apply overhead. Overhead is applied on the basis of machine
hours in the Drilling Department and on the basis of direct hours in the Assembly
Department. At the beginning of 2006, the following estimates are provided for the
coming year:

Actual results reported for 2006 are as follows:

Required
1. Compute the predetermined overhead rates for each department.
2. Compute the applied overhead for the year 2006. What is the underapplied or
overapplied overhead for each department? For the firm?
3. Suppose a job used 4,000 machine hours in drilling and 1,600 direct labor hours
in assembly. If the job size is 8,000 units, what is the overhead cost per unit?

Fill in the t-accounts for each situation and label each transaction as Deferrals/Prepaid, Accrual, or Depreciation. Use Unadj. Bal. as the label for the opening balance of each account. Calculate the adjusted balance and use a Bal. posting reference to show the ending balance of each account. Enter each transaction on the first available line in the T-Account.

A T is drawn. The vertical line divides the account into its left and right sides. The left side of the T-account is called the debit side and the right side is called the credit side. The account name is at the top, above the horizontal line.

Journalize the adjusting entry needed at December 31 for each situation. Record debits first, then credits. Check your spelling carefully and do not abbreviate. Use account names exactly as given in the Chart of Accounts.
